Two types of layered composite structures - based on an aramid fabric covered with alumina microparticles and on polycarbonate - have been considered. Experimental investigation of the mechanical properties and puncture resistance of the first material was carried out. The results of quasi-static, dynamic, and firearm tests of the composite plates are presented. The minimum distance from a first puncture where the stubbing protection is safe was found by using the digital image correlation method. A FEM analysis of bending and tension of composite plates with a defect of complex geometry was performed. The analytical results obtained are compared with test data. © 2012 Springer Science+Business Media, Inc.
